Notice:
This
is not
a final
specification.
Some
parametric
limits
are
subject
to change.
Note that the port-XC selection bit cannot be cleared by software
when it is once set to “1”. The bit can be cleared only by reset. It is
impossible to write “1” to the port-XC selection bit and the system
clock selection bit at the same time. In addition, the contents of the
main clock stop bit and the XCOUT drivability selection bit cannot be
changed when the port-XC selection bit is “0”.
Figure 67 shows the system clock selection change example when
using the sub clock. When the system clock selection bit is “1” after
sub-clock oscillation starts, the sub clock is selected as the system
clock. Make sure to select the sub clock after the sub-clock oscillation
is fully stabilized.
When the main clock stop bit is set to “1” after the sub clock is selected,
the main-clock oscillation/input stops. By stopping the main-clock
oscillation, current consumption can be further restricted.
When the main clock stop bit is cleared to “0” after the main-clock
oscillation stops, the main-clock oscillation/input restarts.
When the system clock selection bit is “0” after the main-clock
oscillation restarts, the main clock is selected as the system clock
again. Make sure to select the main clock after the main-clock
oscillation restarts and is fully stabilized.
The XCOUT drivability selection bit is a bit to select the drivability of
the sub-clock oscillation circuit and is set to “1” (HIGH) after reset is
released. Make sure to clear the XCOUT drivability selection bit to “0”
(LOW) after the sub-clock oscillation is fully stabilized.
